# --description--

Nel quarto elemento `tr`, aggiungi un elemento `th` con il testo `Total Assets`. Racchiudi il testo `Assets` in un elemento `span` con l'attributo `class` impostato su `sr-only`.

Poi, aggiungi tre elementi `td` con il seguente testo (in ordine): `$579`, `$736`, `$809`. Dai al terzo elemento `td` un attributo `class` con il valore `current`.

# --hints--

Il quarto `tr` dovrebbe avere un elemento `th`.

```js
assert(document.querySelector('tbody')?.querySelectorAll('tr')?.[3]?.querySelector('th'));
```

L'elemento `th` dovrebbe avere il testo `Total Assets`.

```js
assert(document.querySelector('tbody')?.querySelectorAll('tr')?.[3]?.querySelector('th')?.innerText === 'Total Assets');
```

Dovresti racchiudere il testo `Assets` in un elemento `span`.

```js
assert(document.querySelector('tbody')?.querySelectorAll('tr')?.[3]?.querySelector('th > span')?.textContent === 'Assets');
```

L'elemento `span` dovrebbe avere l'attributo `class` con il valore `sr-only`.

```js
assert(document.querySelector('tbody')?.querySelectorAll('tr')?.[3]?.querySelector('th > span')?.classList?.contains('sr-only'));
```

Dovresti avere tre elementi `td`.

```js
assert(document.querySelector('tbody')?.querySelectorAll('tr')?.[3]?.querySelectorAll('td').length === 3);
```

Il primo elemento `td` dovrebbe avere il testo `$579`.

```js
assert(document.querySelector('tbody')?.querySelectorAll('tr')?.[3]?.querySelectorAll('td')?.[0]?.textContent === '$579');
```

Il secondo elemento `td` dovrebbe avere il testo `$736`.

```js
assert(document.querySelector('tbody')?.querySelectorAll('tr')?.[3]?.querySelectorAll('td')?.[1]?.textContent === '$736');
```

Il terzo elemento `td` dovrebbe avere il testo `$809`.

```js
assert(document.querySelector('tbody')?.querySelectorAll('tr')?.[3]?.querySelectorAll('td')?.[2]?.textContent === '$809');
```

Il terzo elemento `td` dovrebbe avere l'attributo `class` con il valore `current`.

```js
assert(document.querySelector('tbody')?.querySelectorAll('tr')?.[3]?.querySelectorAll('td')?.[2]?.classList?.contains('current'));
```
